Schottky barriers on ZnTe

Abstract
Metal surface barriers consisting of gold, nickel, tantalum, and aluminum on zinc telluride have been investigated. The behavior of gold and nickel barriers agrees with simple thermionic Schottky barrier theory. The barrier height found for gold is 0.64 eV and for nickel 0.65 eV. Tantalum and aluminum barriers were found to have characteristics dominated by recombination currents. The barrier height found for tantalum is 1.50 eV and for aluminum 2.00 eV.
